Description

Self-locking fixing device for seismic bracing and pipeline Technical Field

[0001] This utility model relates to the field of seismic bracing equipment technology, and in particular to a self-locking fixing device for seismic bracing and pipelines. Background Technology

[0002] When installing elevator guide rails, anchor bolts are needed for quick positioning and locking. Anchor bolts are classified according to different anchoring mechanisms, such as expansion anchor bolts, enlarged hole anchor bolts, adhesive anchor bolts, concrete screws, shot nails, and concrete nails, which can improve the stability of the installation equipment.

[0003] Existing technologies have the following problems:

[0004] After extensive searching, it was found that the patent document with application number CN202420949439.8 discloses an easy-to-connect seismic support. This patent can precisely control the radial displacement distance of four sets of pressing plates by adjusting the rotation angle of the hexagonal rotating plate, thereby adapting to pipes of different diameters. The four-way synchronous clamping design ensures that the pipe is fixed in the center and improves seismic stability.

[0005] However, the above-mentioned patents still have some problems in actual use. The most obvious problems are that the structure is complex, the hexagonal plate needs to be adjusted multiple times during installation, the operation is time-consuming, and the four-way clamping mechanism has high requirements for the roundness of the pipe. If the pipe is slightly deformed, it is difficult to fix it in the center.

[0006] To address these shortcomings, we proposed a self-locking fixing device for seismic bracing and pipelines. Summary of the Invention

[0007] The purpose of this utility model is to propose a self-locking fixing device for seismic bracing and pipelines to overcome the shortcomings of existing technologies.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking fixing device for seismic bracing and pipeline, comprising seismic bracing, chain, chain link and pipeline, wherein a connecting seat is welded to one end of the seismic bracing, and an arc-shaped plate is installed at the lower end of the connecting seat, a through hole is provided through the surface of the connecting seat, and a chain is inserted through the through hole, one end of the chain is fixed to the seismic bracing, and the other end of the chain passes around the pipeline and is locked to the chain link by a locking hook.

[0009] Preferably, the inner side of the arc-shaped plate is fitted to the outer wall of the pipe, and its curvature matches the outer diameter of the pipe.

[0010] Preferably, the through hole is elliptical in shape.

[0011] Preferably, the circumference of the pipe is less than the length of the chain.

[0012] Preferably, a buffer pad is provided between the arc-shaped plate and the pipe.

[0013] Preferably, the cross-sectional area of ​​the through hole is larger than the cross-sectional area of ​​the chain.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a chain, with one end connected to the seismic brace and the other end wound around the pipe a certain number of times before a locking hook is fixed to the corresponding chain link. This allows for convenient and stable fixation of the entire seismic brace to the pipe, making it suitable for pipes of different specifications. It is highly adaptable, simplifies installation steps, and can be adapted to pipes of different diameters without complex adjustments. Furthermore, it features a simple structure, stability, reliability, and low operating costs.

[0016] By setting an arc-shaped plate, the contact area between the seismic support and the pipeline can be increased, making the seismic support and pipeline more stable and less prone to loosening. Attached Figure Description

[0025] Please refer to Figures 1-3. The self-locking fixing device for seismic bracing and pipeline includes seismic bracing 1, chain 5, chain link 7 and pipeline 8. One end of seismic bracing 1 is welded with a connecting seat 2, and an arc plate 3 is installed at the lower end of the connecting seat 2. A through hole 4 is provided through the surface of the connecting seat 2, and the chain 5 passes through the through hole 4. One end of the chain 5 is fixed to the seismic bracing 1, and the other end of the chain 5 passes around the pipeline 8 and is locked to the chain link 7 through the locking hook 6.

[0026] Taking DN200 pipe 8 as an example, after the chain 5 is wound around 3 times and locked, the contact area between the arc plate 3 and the pipe 8 reaches more than 85%. After vibration test with an amplitude of ±5mm and a frequency of 10Hz, the device did not loosen. Its seismic performance is better than that of traditional rigid clamping structures. During installation, one end of the chain 5 is passed through the through hole 4 of the arc plate 3 and locked on the chain link 7 to complete self-locking, which can adapt to different installation requirements.

[0027] In this implementation scheme: the inner side of the arc plate 3 is attached to the outer wall of the pipe 8, and its curvature matches the outer diameter of the pipe 8.

[0028] Specifically, the curvature design of the arc plate 3 can automatically conform to the surface of the pipe 8, while the rubber buffer pad absorbs vibration energy and avoids rigid impact.

[0029] In this implementation scheme: the through hole 4 is designed to be elliptical.

[0030] Specifically, chain 5 is allowed to adjust its winding angle within a certain range.

[0031] In this implementation plan: the circumference of pipe 8 is less than the length of chain 5.

[0032] Specifically, it can wrap the chain 5 around the pipe 8 in a certain number of turns.

[0033] In this implementation plan, a buffer pad is provided between the arc plate 3 and the pipe 8.

[0034] Specifically, it serves to cushion and reduce shock, while also increasing friction.

[0035] In this implementation scheme: the cross-sectional area of ​​the through hole 4 is greater than the cross-sectional area of ​​the chain 5.

[0036] Specifically, this allows the chain 5 to pass through the through hole 4.

[0037] Working principle: When in use, taking DN200 pipe 8 as an example, after the chain 5 is wound around 3 times and locked, the contact area between the arc plate 3 and the pipe 8 reaches more than 85%. After vibration test with an amplitude of ±5mm and a frequency of 10Hz, the device did not loosen. Its anti-vibration performance is better than that of traditional rigid clamping structures. During installation, one end of the chain 5 is passed through the through hole 4 of the arc plate 3 and locked on the chain link 7 to complete the self-locking. It can adapt to different installation requirements. The curvature design of the arc plate 3 can automatically fit the surface of the pipe 8, and the rubber buffer pad absorbs vibration energy and avoids rigid impact.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
